Trying to get a handle on the theory of the 9th and 6th chords. Since the root note is not being played does that imply that for example the G6 chord is also the A9 chord and what you are playing depends on the context of the song?

I don't know for sure, because I can't find the original ad, but I found something that pointed me to this song. It sounds similar to what I remember anyway, at around the 3:15 to 3:25 time frame one of the guitarists does what possibly looks and sounds like the gospel slide Justin teaches. May not be exactly because it is beyond my knowledge at this point, but sounds similar to what I remember the commercial sounding:

Yeah Typo but T bone is the original.The Allman version has more chord variations and chord subs.I personally play it both T bone and the Allman way.both use the G9 no root which looks like the B minor 7 flat 5.If they played stuff like this in Church I think they could charge admission LOLJesus!!!!! Warren is a monster player, good singer and writer as well.PeaceAlbatross an old Peter Green song does not use these chords, tis a great song mainly based on E major no fancy chords in the song.Simple sounds good if you hear fancy chords hear your ears are better than mine, I hear two chords E major and F# minor as the basic chord yeah he plays an A and the G# minor over Open E but that is just about it.http://www.youtube.com/watch?v=3oSlZMe2WIo

The root is being play by the bass player or another instrument.Justin gave the interval of the chord this and the sound is what matters.b7, 9, 5 will become R, 3, 6 by moving to up a whole tone or step.

Lap steep guitar tune to the 6th chord, which is where I think this comes from .There is also 3 inversion for the chord this first was the b 7th but you can also play the inversion with the 3rd or the 5th as the first note.so you can moving these chords up a whole tone turn them into the major 6th chord.the key thing to notice is that while playing the 9 no root which is an extended Dom 7th chord is the tone , it is kind of pushy restless more aggressive and the 6 chord is sweeter in sound.yeah confusing cause it is the same shape but unless you are hearing unpaired you hear there is a great difference in the two chords.it is base on the root and how it relates.This is an advanced subject you will need to study more theory to get it but the shapes and the lesson can be used , I used this for many years cause it sounds good .This is what Justin was intending all to do as well.Peace
